When ice :is used as a retrigeratory agent in boxes. ice cream cabinets and sodalifountain compartments there is ordinarily a con-r densate which yshould be removed to prevent deterioration of the rmaterial forming; the` walls of the box, cabinet or,compartment.`y

My invention aims to provide an ice box construction which affords `a chamber in whichk the condensate may accumulate and be readily removed as it accumulates. 'p

My invention also aims toprovide a cabinet construction -for soda water Jiountains which will provide anice compartment ior ice cream containers or cans, and another compartment to receive cold water from the ice compartment, so that the cold water may be used for cooling bottles or other containers placed therein. The waterk receiving compartment of the cabinet is constructed so that the supp'lyo'f wat-er thereto may be controlled, also the outlet ot' water, and all oi this `is accomplished without changing any standard design ot cabinet and without materially increasing the cost'ot production.

My invention will be hereinafter described and reference willl now be had to the drawing, wherein Figure 1 is aL perspective view ot' a soda water fountain.'having` a cabinet 'or ice bonr in accordance with my invention;y

Fig, 2 is alongitudinal sectional view oi? the cabinet or ice boxgand I `Fig. 3 is an enlarged vertical sectional view of a detachable overflow pipe or connection for the` drain compartn'ient oi the cabinet or ice box.

In the drawing', the reference numeral denotes an outer casing' havingv legs or supports 2 restingfon atloor 3, and said'casing is provided with a transverse partition ,Li dividing said casing' into two compartments, one larger thanl the other. The inner walls ol` the casing compartments are each provided with a metallic lining 5 and in each compartment is a metallic inner casing 6. Between the inner casing 6 and the metallic linings 5 are linings ot water proof and insulation material 7, preferably in the formof blocks or sections of cork, asbestos or any material possessing waterproof and insulating characteristics which will more `or less isolate the inner casings y6 from the outer casino'.

One of the inner casings is adapted to hold a rclrtrgerant, as ice S in which may he placed an ice-cream container or other yreceptacle 9.. l y I f The other inner casing is adaptedto holdr Vcold ywater lOin which may be placed bottles 11 orgother receptacles, and on account ot such cooling agents causing condensation,

waterproof spacing kmembers r12 have rbeen placcdnbetween the bottom of the outer casing and the" linings of insulation material at the bottoms of the inner casings.. The spacing members ,1Q may be in the'form ot perforated corrugated galvanized sheet metal n with the corrugations f affording-1r spaces for the accumulation of condensate adapted to be L.removed through drain pipes lextending through the bottom ofthe outer easing 1 andthe *floor 3. The corrugated metal may be insma'll loosely joined pieces which will readily permit any condensate to pass therebetween andr reach the inner tace 'of the lining 5 and flow ott through the pipe kThese drain pipes orconnections may yhave traps 1st preventing air-.from entering the condensation chambers in the outer casing' and with said chambers sealed, the air therein will serve for insulating purposes. f y

Extending from the ice holding inner casing into Athe water holding inner casingl is a. drain pipe or connection 15, which` extends through the partition 4 and has a: conventionalform of valve 16 within the water holding casing. c The admission of ice water to the water-holding casing may be controlled by the valve 16, and in order that vwater may be drained from the waterholding casing or a predetermined level of water maintained therein, said casing is provided with a drain pipe or connection 17 and an overflow pipe Lor connectionl; The drain pipe 17 is provided with a valve 19 to con'-v trol the drain of water through' saidk pipe and said pipe has a tunnel shaped mouth or seat-2O at the `bottom of the waterholding i casingto receive the conical end 21 of the overllow'pipe ory connection 18. NVith this pipe or connection in place, as shown in Fig. 2, and the valve 19 opened, the level of water will be maintained at the upper end of said pipe or connection. Should it be desired to remove the water the overflowk pipe 18 cank be removed. f

In Fig. 1 I .have shown the ice box construction embodied ina small sodakwater 'Fountain having faucets 22, 'davor contain ers' 23, and a drain board 24. This drainv lboard may bevlocated at the upper end of the Water holding inner Casing at one end of the fountain, While the ice holding compartment may occupy the greater part of the opposite end of the fountain. The last mentioned compartment or casing may be normally closed by a lid 25 contributing towards the support of the ice cream container or receptacler9 surrounded by the ice 8.

In such refrigeratory boxes, showing condensate, Whichl have examined, the insulation material is very often soaked and loses, to agreat extent, its insulating qualities, Whereas boxes in accordance with my invention show that the insulation is perfectly dry and there is no deterioration due to clampness or the accumulation of any condensate. This provides a better refrigertor or ice box and does not materially incasing', an inner casing', a lining` of insula-V tion material about saidinner casing7 spacing means between the'lining of insulation material and the bottoni of said outer cas'-,

ing, and a drain connection for each casing. In testimony whereof I atlix my signature.
